here's a m.c.q plz choose the correct option &explain the same:-a planet is moving in an elliptical orbit.if T,V,E &L stands for its kinetic energy,gravitation potential energy,total energy, total energy &angular momentun about the centre of earth,then: (A)T is conserved (B)V is always positive (C)E is always negative. (D)magnitude of L is conserved,but its direction changes continuously.
